I have a 2007 Chevy Silverado 2WD that has been lowered front 3″ and back 5″. The shop that did the lowering job installed Calmax Shocks in the rear. The model of shocks are 2200C. To date on the driver side I have blown 2 shocks since 2007. Am I using the correct shock?
You have the correct shock part number for your 07 Silverado with our kit. It is very unusual to suffer blown shocks like you have. It’s even more unusual to have the replacement fail. Please check to make sure your shocks are not also the bump stop for the rear suspension. If they are acting as a bump stop it will blow out the valving and the shocks, plain and simple won’t dampen anymore. Beyond that, inspect the chrome shafts to see if they are pitted or nicked which would harm the oil seals on the top of the shock and cause oil leaks and loss of the gas charge.
